The Increase Decimal and Decrease Decimal commands let you control how many decimal places are shown in a cell. They do not change the actual value in the cell. These commands only affect how the number is displayed.

When you decrease the decimal, the value will look rounded to the chosen decimal place. However, the full value is still visible in the formula bar.

These commands may not work with all number formats, like Date or Fraction. For those formats, the decimal display will not change.

This feature is useful when you want to simplify the appearance of numbers without changing their actual values.
